I ask this because I think of the recent switch of Ubuntu to the Rust recode of the GNU core utils, which use an MIT license. There are many Rust recodes of GPL software that re-license it as a pushover MIT or Apache licenses. I worry these relicensing efforts this will significantly harm the FOSS ecosystem. Is this reason to start worrying or is it not that bad?
IMO, if the FOSS world makes something public, with extensive liberties, then the only thing that should be asked in return is that people preserve these liberties, like the GPL successfully enforces. These pushover licenses preserve nothing.
Permissive license means that whoever (say a corporation) modifies some code and release a software from it, they are not obligated to release the modified code under the same license. Which means they can use Open Source software to make proprietary software, make money off it, and the community receives nothing back for their labor.
GPL forbids this. With GPL anyone can still modifes the code and release a software from it. But it obligates that the modified code must be released as GPL too. So GPL guarantees that the community benefits.
The act of choosing a license political one. Are you willing to provide unpaid labor for corporations? Or do you want your code to benefit communities?
